ABSTRACT
<p><b>OBJECTIVE</b>To investigate the level of the patients perceived control of asthma (PCA) in South China and analyze the risk factors contributing to inadequate PCA.</p><p><b>METHODS</b>A total of 150 asthmatic out-patients consisting of 86 males and 64 females aged 19-65 (38.6∓11.7) years were enrolled in this investigation. The patients were asked to complete questionnaires of the demographic data, perceived control of asthma (PCAQ-6) scales, asthma control test (ACT) scales and Standard asthma-specific quality of life [AQLQ(S)] scale. The data of spirometric measurements, blood cell count and induced sputum cell count were also collected.</p><p><b>RESULTS</b>All the 150 asthmatic out-patients recruited completed the questionnaires and examinations. The PCAQ-6 scores ranged from 10 to 26 (18.75∓3.42) in these patients (18.6∓3.28 in male and 18.95∓3.6 in female patients), significantly lower than those reported in other countries (P<1). PCA was positively correlated to the level of asthma control (r(p)=0.377, P=0.000) and AQLQ(S) scores (r(p)=0.675, P=0.000). Multiple linear regression showed that PCA was positively correlated to FEV1% and blood neutrophil counts, and inversely to asthma duration.</p><p><b>CONCLUSION</b>The level of the PCA appears inadequate in South China. The PCA can affect the level of asthma control and asthma-specific quality of life. The factors contributing to inadequate PCA include primarily asthma duration, lung function and blood neutrophil counts.</p>
